If you are getting a "Simconnect error", then you have a Simconnect problem, which is totally unrelated to any of our products and they cannot fix automatically a problem with it. A correct FSX installation must have Simconnect, which is part of FSX, fully working, otherwise NO addon module will ever run.
But since you haven't said which sim you use ( FSX, FSX:SE, P3D ), it's difficult to understand why you Simconnect is not working.
